Question

Photons with energy 5 eV are incident on a cathode C, on a cathode photoelectric cell. The maximum energy of the emitted photoelectrons  is 2 eV. when photons of energy 6 eV are incident on C, no photoelectrons

Options

A.3 V
B.- 3 V
C.- 1 V
D.4 V

Solution

= 5eV - 2eV = 3eV
⇒ - VS = ⇒ VS = - 3V
